I have read on archive.org that prelinger archives are public domain and it also could be used for commercial use. But I would like to make sure about it. Am I right? Is there no problem on use prelinger archives for commercial use?
It's seems the creative commons license listed has been "retired", just click on it and see...does this have any impact on the status of the archive? Will you be attaching one of the other CC licenses to the archive?
